Mensagem para um náufrago - Message to a cast away

A bottle of glass by a lake is taken by the water.
There is no action apart from a slight movement of the waves.
The message inside the bottle is a quote by Gaston Bachelard: "stillness is a happy vibration".
This video-art piece was created by the visual artist Gabriela Gusmão for her individual exhibition called "A Comma in the Infinite" at the Museum of Modern Art of Rio de Janeiro, where the projections took two months, in 2011.
Audio source: water.
No special effects.
Just natural light.
No titles, no credits..
A simple message sent from land to a shipwrecked.
